Abstract
Official abstract text for this publication.
Example embodiments are directed to light-emitting devices (LEDs) and methods of manufacturing the same. The LED includes a first semiconductor layer; a second semiconductor layer; an active layer formed between the first and second semiconductor layers; and an emission pattern layer including a plurality of layers on the first semiconductor layer, the emission pattern including an emission pattern for externally emitting light generated from the active layer.
First claim
Opening claim text (preview).
What is claimed is: 1. A light-emitting device (LED) comprising: a first semiconductor layer of a first impurity type; a second semiconductor layer of a second impurity type; an active layer between the first and second semiconductor layers; an emission pattern layer on the first semiconductor layer, the emission pattern layer including a plurality of layers and having an emission pattern that externally emits light generated from the active layer; a metal layer under the…
